Valgrind is an instrumentation framework for building dynamic analysis tools. There are Valgrind tools that can automatically detect many memory management and threading bugs, and profile your programs in detail. You can also use Valgrind to build new tools.

Code:

valgrind /usr/bin/vlc

not being able to scroll all the way up to the initials commands.Maybe as i issued quite a few commands the Terminal became saturated?several commands with hundreds of lines as result(should i quit on each hight-verbose-result and relog after having copied and pasted of course the result?)just the $ vlc -vvv /home/linuxlibre/Téléchargements/'Peuterey Integral Ridge.mp4' gave a result of 182 lines!My question is as i have been encouraged to file a bug report after installing

Is there a way scrolling up:ie giving maximum verbose in the terminal(i guess i have a 500 line mx capacity but the info ,rushs so fast and is so "quantitative that't it's hard to know) if i encounter such situation again.i have tried:

Don't understand anything. Mine works fine on Hatrack 20 and freed-ora 20!
For the terminal: I think you use your distro in French; so open your terminal and then: Edition-->Préférences du profil-->Défilement and you configure as you like it.

I don't understand either why all was working fine on Freedora19 and not
on F20.Vlc works's fine on GdNewHat'Hatrack'
The explanations i've been given are:

The problem seems to be with the interface cairo is breaking down there for some reason and you using another one the svlc shows it works...&...It is a bug, VLC hardware acceleration is interfering with the desktop compositor that is why it crashes or so I think it is, seriously don't take my word for it, test everything and see it for yourself.

As far as the Terminal that's exactly what i was looking for ;-) i got
mislead into
terminfo - terminal capability data base
Terminal > Edit > Preferences > Scrollback was on 1000
Lines/have put it 2500...
after issuing several commands i guess i was above the capacity.Thus not
being able to scrollback to the 1st command.
